STOWING AND LOWERING BOATS.

Specification of Letters Patent.

Patented'Feb.4,1913.

Application filed June 1, 1912. Serial No. 701,054.

T 0 all whom it may concern:

Be it known that'l, HENRY ST. G. LIN.D'- SAY. a subject of the King ofGreat Britain, residing at Ottawsi,.in.the Province of Ontario, Canada,have invented certain new and useful Improvements in the Stow ng andLowering of Boats, of which the following is a specification.

v invention relates to improvements in the stowing and lowering of boatson board ship as described in the present specitieation and illustratedby the accompanying drawings that. form part of the. same.

The invention consists essentially of a boat ehoek mounted through aswivel on a carrier provided with brake meehanisni and (amine rollerswhereby said carrier is adapted to run on rails or launching wayssuitably secured to the ship (leek; said rails being arrangedtransversely of said (leek whereby. in rombinat-ion with davits. boatscan be lowered from one or both sides of a ship. The movement of theboats on the rails being eontrolled by said brake inertiauism..\pertnres in said rails adapted to reeeive stops for firmly seem-hr;the boats when not in use.

The objeet of my invention is to provide a new. simple. etteetive. andinexpensive means for launrhing one or more boats from a ship under alleonditions oi weather.

further objet-t is to provide. means for slowing a number of boats onportions of the le kotherwise not used andin suth mailn-zu' that. whenrequired. they will be easilv aeressible and readily lowered. it newessary irom both sides of the ship simub taneonslv.

'ith. these and ther objeets in view referenre now had to theaet-oiupanying drawings in \\'lll('ll like numerals of reter (nee indiate eorrespondin; 'parts in eaeh figure. and in \\'lll('lt.

-l"i';{nre 1. is a plan view of a series of boats stowed side by side onrails extend 111;: transversely aeross the ship. Fig. 2. is a sideelevation of a boat mounted on my deviee. Fig. l. is an end view partlyin seetion of my invention. Fig. 4. is an enlarged front view showingrelative. positions of roller and operating rain lever. Fig. 5. is aplan view of a rail with (-leats or stops in po ition.

. Referring to the drawings, 1 is the deck of the ship. 2 the boat and 3(lavits.

4 are rails arranged transversely across thedeck 1 and secured fixedlythereto in any suitable manner. i

5 is the check formed with a step-bearing 5 adapted to engage with thesupporting pin 6 on the earrier ti. Said supporting pin forming a swivelwith the chock. The top of the former being threaded to receive alock-bolt if necessary to more firmly se ure the latter. The carrier 6is adapted to fit over, and on one side at 11, to overlap. the tread ofthe rail, traveling on same by means of the rollers 99 earriod in saidearrier on the axle 10. The other side of the carrier 6, is formed at 6to carry a lever 7 and the friction roller 8, on the axle 8'. forming abrake for said Farrier; whereby its travel on the rail is fullycontrolled and regulated.

12 -t2 are cleats or stops formed with pins lit-A3 adapted to engagewith the apertures 14 in the rails. While here shown in Fig. 2-3 as one.on 011(11 side of the carrier (1. two each side may be used withadvantage. The boat being thus held more set-urely in position whennotin use. These stops are provided with Ihant-lling means in the form ofrings for pulling them up when the boats are about. to be lowered. Theapertures H may he continued through the base ol the rail it neeessary.

'lo launeh the boat. thestops l2- ll' are first pulled out when the boaton its ehook will slide down the rails quiekly and smoothly by means ofthe, rollers 9-9'. The length of the davits with suspending taekle beingarranged the sliding will be avt-oniplished without any jerky action. Tocheek the boat in its travel or control its paee. so that. it will notpass out too quickly, it is only neeessary to' apply the brakenieehanism by Pt2ltlfl;j the lever 7, which in turn will operate thefriction roller 8 against the under part of the rail. To replan theboats after being hoisted from the water, they are lowered on to thewaiting ehoeks. eat-h pair of same on being loaded. being moved-up therails and secured in their plaees hv replaeing the stops 1- \Vith myinvention any number of boats that can be aeoommodated side. by side onthe rails may be lowered on either side of the ship, as required.

The brakeaneehanism consists more partieularly of the lever 7 adapted toengage the square end of the axle 8. Said axle being adapted to theeccentrically mounted roller 8, fixedly secured thereto said axle beingprovided at 8 with a suitable bearing to work in freely.

The operating handle of the lever 7 can be made detachable for moreconvenient storage, and is provided with a friction pin 15 to moresecurely retain it in position.

What I claim for my invention is LA device of the class describedcomprising launching-rails, chocks, with swivels, mounted on carriers,rollers in said carriers adapted to travel on said rails; one side ofthecarrier overlapping said rail, a friction brake supported by theextended other side of the carrier; operating means for said brake;apertures in said rails adapted to receive securing means for stops orcleats adapted to hold said chock-carrier securely in position.

2. In a device of the class described the combination with launchingrails of a chock mounted through a swivel on a carrier adapted to travelon said rails provided with brake-mechanism whereby the travel of saidchock is controlled.

In testimony whereof I have hereunto signed my name in the presence oftwo subscribing witnesses at the city of Ottawa, Province of Ontario,this 18th day of May,

H. ST. G. LINDSAY. Witnesses:
